Calgary-based pipeline company Enbridge said Thursday it will build a $370-million pipeline to connect a Suncor Energy oilsands plant to Enbridge's system in the oilsands region of northern Alberta.

The 95-kilometre Wood Buffalo pipeline will run parallel to the Athabasca line that Suncor currently uses and will carry increased production from the oilsands. It is expected to be in service by the middle of 2013.

Enbridge is the largest operator of pipelines in the oilsands region.

The latest project will bring to $1.6 billion the amount it has spent on expanding its system of pipelines and tanks in the area.

Enbridge has been grappling with the cleanup of 19,500 barrels of oil that spilled into the Kalamazoo River in Michigan after a break in its pipeline there on July 26.

It shares were down 49 cents to $52.21 at midday Thursday on the Toronto Stock Exchange.
